Filed: 1986-12-18
Abstract: PURPOSE:To achieve a higher measuring accuracy, by a method wherein a measuring water is turned into vapor to electrolyze and hydrogen obtained is introduced to measure radioactivity in the hydrogen. CONSTITUTION:A heated water vapor tank 22 turns a measuring water into vapor to remove water scale or the like existing in the measuring water and then, the water vapor is supplied to a heating tank 24. A solid electrolyte tank 26 has a solid electrolyte substance 26c and when the water vapor heated with the heating tank 24 is passed through the solid electrolyte tank 26, a reaction occurs at a cathode 26a from H2O+2e<-> H2+O<2-> to obtain a hydrogen gas while an oxygen gas is generated. Then, a cooling tank 28 maintains hydrogen obtained from the heating tank 24 at a normal temperature while drying it and an ionization chamber 30 introduces the hydrogen to detect ionization charge due to tritium in the hydrogen. A measuring circuit section 34 measures radioactivity according to the said ionization charge. In this case, with separation of the most of moisture hydrogen gas, the concentration of tritium can be determined accurately in the measuring water.

Abstract: PURPOSE:To reduce the using amount of a bonding material and to suppress the effect of change with time on the solidified bonding material, by tapering a pipe, through which a piece of optical fiber is guided out of a case so that the tip faces a light emitting element, in the inside of the case, and fixing the optical fiber at this place with the metallic bonding material. CONSTITUTION:A pipe 21 penetrates through a side wall 3a of the main body 3 of a case in correspondence with a pipe 9. The diameter D1 of the protruding part of the pipe 21 at the outside of the case is the same as that of the pipe 9. The protruding part of the pipe in the case comprises a tapered part 21a and a small-diameter part 21b. The inside of the small-diameter part 21b is filled with a solder 22 as a metallic bonding material so as to surround a piece of optical fiber 14. Thus the airtightness of the lead-out part of the optical fiber is secured. The amount of the solder 22 is very smaller than the amount in a conventional device. A thickness t1 of the solder surrounding the optical fiber 14 in the direction of the diameter of the pipe is an thin as a fraction of the conventional device. Therefore, the deviating amount of the optical fiber 14 due to the change with time of the solder 22 such as segregation creep and the like is suppressed to a lower value. The effect to the fixed part of the tip of the optical fiber is suppressed, and the initial characteristics can be maintained for a long period.

Title: Dynamic pressure type rotation shaft bearing unit
Inventor: SHODA HIROYUKI
IPC: F16C33/24
Filed: 1988-11-30
Abstract: PURPOSE:To improve the accuracy of radial rotation by forming aggregate groups of minute, grinding marks, which are parallel to the inner peripheral surface of a bearing, onto the bearing part, which is made of ceramics and which has a truly round shape and a smooth inner peripheral surface, and inserting a rotation shaft, which is made of ceramics and which has a truly round shape and a smooth outer peripheral surface, into the bearing part. CONSTITUTION:A ceramic-made rotation shaft 2 is inserted in a ceramic-made bearing part 1, while aggregate groups 4 of minute, grinding marks 3 which are nearly parallel to the shaft center line, are formed on the inner peripheral surface of the bearing part 1. The roughness of the inner peripheral surface of the bearing part 1 should be 0.8mum Ra or smaller, while the roundness of the bearing part 1 should be 1mum and under. Both roundness and surface-roughness of the shaft 2 should be the same as the above. During the operation, the rotation shaft 2 inserted in the bearing part 1 rotates in an eccentric manner, while the amount of air inclusion caused by the grinding marks increases. As a result, the air between the rotation shaft 2 and the bearing part 1 moves in the same direction as that of rotation of the shaft 2, thereby producing pneumatic pressure. Since the rotation shaft 2 is supported by this pneumatic pressure, highly accurate radial rotation having less friction and no run-out of the rotation shaft 2 can be obtained.
